Established in 1992 as the "Yueqing Shuguang Fuse Factory," our journey spans over three decades in the heart of China’s electrical capital—Yueqing, Zhejiang. As a premier power technology enterprise, we integrate research, development, production, and global sales service.
We are designated by the Ministry of Electric Power Industry to manufacture high-voltage fuses, current-limiting fuses, and transformer protection devices. Our brand "Shu Rong" is synonymous with safety and precision in the power distribution sector.
The modern power grid requires intelligent protection. Our general-purpose fuses are evolving to support smart grid infrastructures, offering higher precision and faster response times to prevent cascading failures in complex digital networks.
With the rise of Electric Vehicles (EV) and Solar energy, the demand for DC high-voltage fuses has skyrocketed. We manufacture specialized EV fuses that withstand the rigorous thermal cycling of fast-charging stations and battery packs.
As industrial equipment becomes more compact, the "Miniature Fuse Link" has become a critical component. Our 8*150mm designs offer maximum protection in minimal space, meeting the strict DIN and IEC standards.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is backed by our compliance with every major international standard. Whether you are sourcing for a project in Europe, America, or the Middle East, our products meet:
All products have passed rigorous testing at the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center and the Xi'an High-voltage Electrical Apparatus Research Institute. This ensures that every general-purpose fuse leaving our factory can withstand the harshest environmental and electrical stresses.
Global procurement teams from Southeast Asia, Africa, and Europe look for more than just a component; they seek reliability. BestGeneralPurposeFuses act as the "silent guardians" of industrial assets. Our solutions are deployed in:
Protecting distribution transformers from secondary faults and internal short circuits.
Ensuring safety in high-load industrial environments and motor starting circuits.
Stabilizing solar inverter outputs and wind turbine collection systems.
Drop-out fuses and lightning arresters for overhead lines in rural and urban grids.
Wenzhou Shuguang Fuse Co., Ltd. represents the peak of Chinese manufacturing efficiency combined with global engineering standards. While we vigorously develop new products, we remain committed to process perfection. Our advantage lies in:
In recent years, our economic and social benefits have improved significantly through the continuous deepening of our quality management system. The "Shu Rong" brand isn't just a label; it's a promise of performance. We utilize advanced testing rigs for impulse voltage, power frequency withstand, and partial discharge testing.
Our research team focuses on the XRNP current-limiting fuses and H.R.C. (High Rupturing Capacity) technology to ensure that in the event of a fault, the fuse clears the circuit within milliseconds, protecting multimillion-dollar assets.
Our products are exported to various provincial power companies in China and regions including Southeast Asia, the Middle East, Africa, and Europe. We sincerely welcome customers from home and abroad to discuss cooperation and work together for the prosperity of the electric power industry.
